LOOK.

Speclflcation of Letters Patent.

Patented Jan. 16, 1917.

of New York, have invented a new and Inn-'- roved Look, of which the following is a 1111, clear, and exact description.

This invention relates to builders hardware and has particular reference to looks for doors or the like, and especially to looks which are so constructed as ,to resist efforts a to open the same surreptitiously by force ap lied in any direction.

mong the objects of the invention, therefore, is to provide a lock construction ineluding a keeper adapted to be secured preferably" to the door frame and a lock easing carried by the door or other movable mem-' her, said casing carrying a movable bolt having one or more hooks or fingers slidable into interlocking engagement with portions of said keeper, the direction of move-.

ment of said fingers being transverse to (th longitudinal axis of the casing.

' Another objector the invention is to improve the means for manipulating the bolt from either the inside or outside of the door,

position of its movement, and -indcpend,.

said means'including a catch carried by'the bolt and serving to lock the same in either ently movable actuators cooperating with said bolt and catch.

The foregoin and many other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of refer-v ence indicatecorresponding parts in all the views, and in which Figure 1 is a side elevation of the improvem'ent complete shown in locked position on the inner side of a door; Fig. 2 1s a theg bolt and controlling means for. the bolt horizontal longitudinal section substantially on the broken line 2-2 of Fig. 3'; Fig. 3 is a sideelevation of the lock casing showing and also one ofthe' actua'aiirs therefor, parts being in section onthe lina 343ml? Fi 5;

Fi 4' is a view similar to Fig 8 but 1ndi-..

catingthe boltinia changed position with parts in section on'the line 34 of Fig. 5,

the other actuatorj being shown; Fig 5 is a vertical transverse section on the line 55 of Fig. 2; and Fig. 6 is a detail view of the bolt etached. I The several parts of this device may be, made of any suitable materials, and the relative sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the s irit of the invention hereinafter more fol cally claimed. l

Referring more particularly to the draw ings, show at 10 a portionq'f a door frame to which is secured a strong rigi'd keeper 11 having one or-more cars 12 extending from the main ortion of the. keeper in planes perpendicu ar to the door frame, each ear having an eye 13 parallel to the door frame.

y describedand specifi- -I show herein a keeper having two ears and with their eyes arranged coax ally, but as to" a this, as in'other details, I do not with to be unnecessarlly limited.

- At 14 I show "a door cooperating in closed position with the frame 10 and carrying on a slight sagging of the. door or .any other irregularity without interfering "IWlth the free opening or closing movement of the,

loor. The center of curvature of the several guards alines with the axes of .the e ves 13 of the earswhen the door is closed. l

The peculiar form of bolt 19 shown, in

detail in Fig 6 is carried within the casing. l5 and 1s movable within the casing in lines transverse to the longitudinal axis of the casing for locking or unlocking purposes. I

The" outer end of the bolt includes a plu rality of fingers or hooks. 2O housed within the uards aforesaid, the ends of the hooks adjacent guards and pass entirely through the eyes of the keeper earswhen the 'bolt is'in locking position.- In this position the extreme endv of a ,hook projecting from one adapted to span 'thespaces between- 1 guar lreaches'intotheunterlor of an adjaeent guard as shown in dotted linesin Fig. -l. In this position. with the hooks extending' through the ears ol the keeper, there is no )(lSt-dhllll) for the lock to be sprung or the door-do he opened by the use of a jimmy or otherwise because the interlocking eooperation between the keepers. and the hooks resists any relative movement between the keeper and the bolt mechanism.

Any suitable means may be provided to manipulate the bolt so as to muse the hooks thereof to open or close. the. spaces between adjacent guards; As shown herein I prefer to make the bolt 'with a substantially flat body movable in a plane parallel to the fixed wall ot' the. easing 15. said bolt being formed preferably with a pair of ribs 31 and :22 on opposite faces of the bolt and cooperating respectively with shoulders 23 and 24 ot' the casing whereby the bolt as shown herein limited in its movements in lines parallel to the d or frame and trans-- verse to the axis of the easing. In other words. the bolt is adapted to slide in a plane parallel to the inner face of the door and in a direction longitiulinally ol' the door stile. The cooperating ribs and shoulders provide for long bearing points for the bolt. insuring that the bolt will move freely and reliably without binding or erampinq'.

The Flat shank 2.) of the. bolt.- is provided -ut its inner end with a pair oi spaced lugs 2 having substantially twice the depth of the thickness of the shank '35 as shown best in Fig. 2. stud L? is secured to the 'face of the shank :25 inwardly from the lugs 26 far enough to :u'eonunodate a movable catch 28. The catch is pivoted at one end at 28 to the extension '3!) of the bolt. and has a linger 30 projecting longitudinally and thence laterally between the lugs .26. The square space between the lugs Qt) provides a notch. the bottom of which serves to limitthe swing of the catch toward the stud 27. Except for other features, the outward swinging movement of the. catch will be limited by those parts of the lugs which project laterally from the main portion of the shank 25. A spring 31 is anchored in the pivoted end of the catch and tends by cooperation with the stud 27 to hold the catch in the r'ull line position shown in Figs. 3 and i. Thepivotal connection betweenthe catch and the shank extension 29 is preferably by way of a pm formed on or secured to the catch and extends into a socket 29 formed in the extension. By hooking the spring '31 beneath the head of the stud 27. the teudenev for the catch to bGCOlDEdiS placed is prevented in a simple and practi cal manner. I a

The extension 29 has a toe 29 which strikes against :1 lug 32 formed on the intelior. otthe casing and thereby limiting the movement of the bolt in open position,

as shown in Fig. 53. The shank has a. heel 33 on the opposite side from the toe adapted to abut against another fixed stop :24 in'thc opposite side of the casing when the bolt is shifted to the closed position as shown in Fig. t. in other words. the bolt slides along the shoulders 23 and J-lbetween the limit stops or lugs 32 and. Il-l. The books 3H also glide along the inner walls of the U-shaped guards during sui-h movements of I the bolt. The catch has on its edge, remote. from the books 20. a lag 33.") which engages directly with a post 36 carried by the inner surface ot the main wall of the casing and to which the opposite wall or plate 3'? of the easing is adapted to be secured, the outer edge 38 of the plate 3? bearing against the outer wall of the shoulder The side of the post next to the 'atch preferablyv the opposite shoulder of the post thereby 9 preventing the aceidental movement of the bolt to locking position.

Any suitable type of actuator may be used to release the catch from the post. and slide the bolt in either direction. Referring to Figs. 3 and 3 I show a, knob 37 journaled in a huhBS' on the main wall of the casing and rigidly secured to the inner end of the shank 39 of the knob an actuator 40 hav ing a. pair of diametrically oppositely extending fingers 41 preferably of equal form and length and adapted to sweep around close to the inner surface of the main wall of the casing upon turning the knob in either direction. To the actuator 40 are connectod a pair of pins 42. A pair of springs -13, the main portions of which are. parallel to each other, extend beneath the-heads of said pins 42 and tend to hold the actuator 40 with its fingers in a direction parallel to the direction of movement of the bolt or in such position that the fingers l1 arc nor;

mally'wcll out, of the way of t'l'ic'lugs 2S. 7

The springs -13 arc anchored'i anyfs'uitahle mannr to the casing as upon a stud 14A. The structure of the pins 42 such that while. the knob and its actuator'rnay "rotate freely in the bearingafl'orde'd'by the hub 38,'the

springs are always retaincdjheneath the heads of the pins and serve tojrestore the actuator to the position shown a i the actuator is turned far enough 't'or' its-pun pose in throwing the bolt. In other words, as soon as the actuator passes the dead ecu-- ter or the llne at right angles to its normal position, the for upon blathgof the""' ms w movementor half rotation of-the actuator. type oflock cylinder the key must be ro'- Looking again at Fig. 3, the rotation of. the tated through a complete circle so that it a 5 actuator in a.clockw1se direction will cause llnoalybe withdrawn after the locking'or un ,,,,xaa i rmgs'betasg inattefinger so has. ample cohtact":
